File descriptors inherited from systemd are always consecutively numbered,
with a fixed lowest "starting" descriptor. This gives the
default starting descriptor. Since this must agree with the value systemd
is using, it typically should not be overridden. (type: int)

File descriptors inherited from systemd are always consecutively numbered,

is using, it typically should not be overridden. (type: int)

A dictionary-like object to inspect to discover inherited descriptors. By
default, None, indicating that the real process environment
should be inspected. The default is suitable for typical usage.

start

An integer giving the lowest value of an inherited descriptor systemd will
give us. By default, None, indicating the known correct (that
is, in agreement with systemd) value will be used. The default is suitable
for typical usage.

Returns

A new instance of cls which can be used to look up the
descriptors which have been inherited.
